Expected Income of New Currency in Blockchain Based on Data-Mining Technology

Abstract: In order to realize the understanding of expected returns after issuance of blockchain new currency initial coin offerings (ICO) and maximize investment returns, in this study, the Semantic Orientation Pointwise Mutual Information (SO-PMI) algorithm is used to create a customer emotional dictionary of blockchain new currency, and collect users’ online comments based on blockchain currency before ICO. The Support Vector Machine (SVM) algorithm is used to construct an evaluation model, analyze and judge users’ c… Show more

“…Semantic orientation pointwise mutual information (SO-PMI) algorithm was applied to obtain the psychological security tendencies, SO-PMI values, word length, and part-of-speech of candidate words in text data. 25,26 Next, candidate words were manually screened. Specifically manifested in: (1) SO-PMI values of candidate words were screened, that is, candidate words with "SO-PMI=0" were selected as neutral words, candidate words with "SO-PMI>0" were used as security words, candidate words with "SO-PMI<0" were used as insecurity words.…”
